<br />At the end of September 1971, Blue Mesa
<br />Reservoir had 532,300 acre-feet of active storage
<br />and a water surface elevation of 7,484 feet.
<br />During April-July 1972, inflow to Blue Mesa was
<br />469,000 acre-feet, or about 59 percent of the
<br />long-time average, This amount of water caused
<br />the reservoir to reach a seasonal high of 7,485
<br />feet and an active storage of 543,300 acre-feet
<br />early in July, During water year 1972, fishing
<br />was enhanced below Gunnison Tunnel by the
<br />flow of not less than 300 c,f.s,
<br />A preliminary flood control diagram for Blue
<br />Mesa is being used to plan and monitor the
<br />routing of the snowmelt runoff. Blue Mesa had
<br />an active storage of 321, I 00 acre-feet on
<br />March I, 1972,
<br />The March I, \972, forecast of the April-
<br />July 1972 inflow to Blue Mesa was 640,000
<br />acre-feet, The flood control diagram showed
<br />that the reservoir could have remained full the
<br />remainder of the snowmelt season; therefore,
<br />the operation of Blue Mesa did not include
<br />releases for flood controL (Chart 3)
<br />Some ice jamming and overflow occurred
<br />along the Gunnison River above Blue Mesa
<br />Reservoir during the last 2 or 3 years, Data are
<br />being evaluated to determine the effectiveness of
<br />the channel improvement program of the Corps
<br />of Engineers to alleviate ice jamming above the
<br />reservoir.
